What does

grep 3dnow /proc/cpuinfo

say on both systems?

They use the same specfile, e.g. go to the bottom of
http://atrpms.net/dist/fc5/lame/

I guess this has to do with the hardware or the kernel used on FC4 vs
FC5. BTW see also a similar bug report on

(In short: lame does the 3dnow check at runtime, but it fails)
